What is Normal Gait?[edit | edit source]
Normal gait is a range of typical gait patterns, found in a healthy population, presenting similar characteristics. Indeed people present a certain degree of variability that is called inter-subject variability is due to differences in age, gender, anatomical differences, and differences in muscular strength.
for example. if we are to assess the gait of an 80 years old man and a 20 years old woman, both without any pathologies affecting gait. They might present completely different gait patterns. However, they will both be considered physiological or normal because their gait patterns will be within the range of normality corresponding to their own population. So when assessing the gait of a patient in physiotherapy, the idea is to confront the gait parameters we find with our own patient against the range of normality established for the corresponding population[1].
Visual Gait Analysis[edit | edit source]
A commonly used method by physiotherapists to investigate gait problems with their patients using a smartphone or any video recording instrument.
Benefits:
- Allows peer-reviewing, showing your colleagues the videos and discussing the presented case
- Reproducible, by taking multiple videos you can track your patient's progression
- Allows observing the gait from multiple angles to detect deviations in multiple plans
Disadvantages:
- Has poor reliability
- It doesn't allow observing high-velocity events, force in moments during walking.
- Subjective, It depends on the observer therefore prone to error
Instrumented Gait Analysis[edit | edit source]
Refers to the collection of quantitative data related to the gait of our patients, such as videography, kinematics, kinetics, oxygen consumption, and electromyography.
Literature suggests that instrumented gait analysis is a valuable tool in clinical practice for the diagnosis, the assessment, and the management of patients affected by conditions altering gait. And in the research field, instrumented gait analysis is often used to evaluate the effectiveness of treatments such as foot orthoses and to explore the consequences of pathologies related to gait, like Rheumatoid Arthritis.
- To apply to clinical practice
- To get familiar with the terminology that is often used in research publications and scientific articles
Considerations to ensure reliability of the results, which refers to the consistency of the results across multiple repetitions and the consistency of the results within a cohort of subjects that present with similar characteristics:
Inter-subject variability
Within-subject variability, which refers to the possibility of obtaining slightly different results with the gait parameters on two different trials, with the same person. This can be caused by small changes in one person's gait from one trial to another due to, for example, stress or apprehension or the desire of the patient to do his best performance. Also, it can be caused by the measurement techniques which give slightly different results under the same conditions[1]
